But this Aluminum Stirling Engine is better! The stirling engine was invented in 1816 as a superior alternative to the steam engine and is powered by the expansion and compression of air when heated and cooled instead of steam. Now you can see this principle in action by running this model on your desktop! Precision design, handcrafted in Germany. 4" x 2 1/2" x 5 1/2". This desktop engine is highly distinctive and collectible. Hurry, limited supply. Perfect engineer gift for the retiring engineer or scientist. A remarkable gift for the guy who has everything or appreciates the finer details in life. (#8547,9057) A ComputerGear Exclusive. Item in stock unless noted above.
